Everybody Lies.

So basically what we found out was that Cuddy has been stalking House for 20 years.

Which makes the whole timeline even more ridiculous. If she was auditing a class where he was teaching, their 11-12 year age difference could be explained (if you squint a little). But if he "cheated" off her, then he would be a student and therefore the whole age/timeline is bullshit.

Hugh was spectacular, wasn't he? That whole detox scene (as implausible as it is) was just incredibly well done and utterly heartbreaking. The man is just incredible.
